High-speed Trilinear Camera

Color line scan camera with conversation capability

The new JAI SW-4000TL-PMCL trilinear camera expands the options for designers of color line scan-based systems to deliver the maximum in color image fidelity, sensitivity, and configuration flexibility. The high performance trilinear technology in the SW-4000TL-PMCL has been combined with a broad set of advanced features to give designers an attractive alternative for applications not requiring the ultimate precision provided by prism cameras. The custom CMOS imager features not just three, but six separate lines of 7.5-micron pixels with two lines each of red, green, and blue pixels. This arrangement makes it possible for the SW-4000TL-PMCL to provide horizontal binning, vertical binning, or both. The sensor’s readout architecture combines the readout of two pixels through a single diffusion node to double the signal without increasing noise, enabling the binning process to dramatically increase sensitivity.

Simplified cabling

Another unique feature is the built-in color conversion capability that allows the SW-4000TL-PMCL to provide native HSI or CIEXYZ color output, in addition to offering conversions from standard RGB to the sRGB or Adobe RGB color spaces, or even to a user-defined custom RGB conversion matrix. The SW-4000TL-PMCL features spatial compensation and tilted view correction functions to maintain proper synchronization and alignment of the R, G, and B channels. In addition, the camera features four separate input lines plus built-in algorithms to support direct connection from up to two rotary encoders. This eliminates the need to connect the encoder via the frame grabber, simplifying the cabling and reducing the possibility of lines being dropped due to issues between the frame grabber and the camera.

Camera link interface

Additional standard features include gain and black level adjustment, manual or automatic white balancing, shading correction, PRNU and DSNU correction, and timestamping of line data. The SW-4000TL-PMCL utilizes a GenICam and Gen-CP-compliant Camera Link interface with Mini CL connectors to output line data. Base, Medium, Full, or Deca configurations are supported, depending on the bit depth and line rate required. 3 x 8-bit and 3 x 10-bit output can be selected. Power can be provided via the Camera Link interface or with a separate power supply connected to the camera’s 12-pin Hirose connector. Two different lens mount options are available – a Nikon F-mount or an M42x1 mount with a 16 mm flange back distance.
